High-Birefringent Fiber Loop Mirror Sensors With an Output Port Probe
IEEE Photonics Technology Letters, 2011Two new configurations of high-birefringent fiber loop mirror with an output port probe are proposed. The two configurations used two couplers spliced between them with unbalanced arms and one output port is used as the probe sensor. The difference between them is that the section length of high-birefringent fiber is located between the two couplers ...

High-birefringence fiber loop mirrors and their applications as sensors
Applied Optics, 2005The reflection and transmission characteristics of a high-birefringence fiber loop mirror (HiBi-FLM), which is composed of a standard fiber coupler and one-section or multisection high-birefringence fibers (HBFs), are analyzed and discussed in detail.

Nonlinear optical fiber loop mirror with feedback using high birefringence fiber in the loop
Nonlinear Guided Waves and Their Applications, 2004The dynamics of a nonlinear optical fiber loop mirror with feedback using CW input and high birefringence fiber is examined. Results show dynamical behavior of the device can be controlled with different input polarization angles.

Liquid-level sensor with a high-birefringence-fiber loop mirror
Applied Optics, 2006A novel liquid-level sensor with a high-birefringence-fiber loop mirror (HBFLM) based on a uniform-strength cantilever beam (UCB) is proposed and demonstrated. Part of the high-birefringence fiber is pasted onto the central surface of the UCB. A hollow suspending pole is utilized to apply force at the end of the beam.

Nonlinear optical loop mirror with low birefringence twisted fiber in the loop
Optics Communications, 1998Abstract The fiber loop mirror constructed from low-birefringence twisted fiber was numerically examined. Nonlinear ellipse rotation effect has been taken into account. Nonlinear switching has been found for the balanced configuration with a 0.5/0.5 coupler.

Sensitivity dependence of fiber loop mirror on the length of high birefringence fiber
Sensors and Actuators A: Physical, 2016Abstract A model of fiber loop mirror with the distinct concepts of sensing length and total length is established. The sensitivity dependence of fiber loop mirror on the sensing length and total length is discussed theoretically and experimentally.

Multiwavelength fiber laser based on a high-birefringence fiber loop mirror
Laser Physics Letters, 2006In this letter, we propose a novel multiwavelength fiber laser based on fiber loop mirror formed by a high-birefringence fiber, a polarisation controller, and a 3 dB directional coupler. By setting the polarisation controller as half-wave-plate, the fiber loop mirror acts as a polarisation-independent wavelength filter; Erbium-doped fiber (EDF ...

A hydrophone based on high-birefringence fiber loop mirror
SPIE Proceedings, 2010A new type of hydrophone based on high-birefringence fiber loop mirror (HiBi-FLM) is proposed and demonstrated. The sensing part is a section of high-birefringence fiber wound onto a hollow metal cylinder fiber. A narrow band light source is used and the detection is done by measurement of light intensity.

Temperature compensation for high-birefringence fiber loop mirror
SPIE Proceedings, 2005We propose a novel temperature compensation method that HBF is mounted on a piece of organic glass. It can lessen its temperature sensitivity to 0.059 nm/K, which are two orders of magnitude lower than that of an uncompensated HBF loop mirror. It is feasible that HBF loop mirror packaged with a large thermal-expansion material is insensitive to ambient
